It is important to support your joints when doing cardio work to check the quality and upkeep your gym/running shoes. It's easy to gauge their lifespan by how dirty they are, but you really should replace them every 3-6 months (especially if you run/walk on cement, or attend aerobic classes regularly).

Good support from your shoes can greatly affect possible knee and hip issues. Plantar fasciitis, can be quite painful, and should be attended to by a physician (you can get recommendations for qualified doctors on the links found on the homepage), but keeping your whole body supported by quality shoes is important. ih.gov/medlineplus/heelinjuriesanddisorders.html

You can find shoes at many sporting goods stores (though the employee’s often seem unqualified teenagers with little to no fitting training), but if you want expert opinions and fitting opportunities, try a running-shoe store. They know the pitfalls of incorrectly fitted shoes, and can help you through the process.

I wanted to say thank you to you all for reading my log for these past 3 years. I've started off on a new adventure so look for me in cyberspace!
Continue with your efforts to create your best health and live life to the fullest!
